In the process of the mass evaluation, the evaluator must
always be carefull to use only the primary information.
While doing this, unfortunately, an accident occurred in the
Ame2003 for the publication of 2001Do08.
In this paper three results were given for 76Ge, 76Se and for
their difference (of higher precision, due to drastically
reduced systematic uncertainties in their combination).
We should have used the 76Se and the 76Ge-76Se result and
not the 76Ge in order not to use twice the same info.
Unfortunately, in the process we accidentaly dropped also 76Se.
Using this 76Se result will give, as expected, improved
values in both 76Se and 76Ge mass-excesses:
76 Ge = -73212.863 (0.091) keV
76 Se = -75251.866 (0.075) keV
We apologize for any resulting inconveniency for the user,
and to the Smiletrap team who has done a wonderful work.

PAIRING ENERGIES (cf. bulletin amdc.061 of January 2006)
In Ame'93 and Ame2003 we calculated pairing energies in tables
available from the AMDC web (not published material):
http://amdc.in2p3.fr/masstables/Ame1993/rct3_rmd.mas93
http://amdc.in2p3.fr/masstables/Ame2003/rct7.mas03
The quantities Dnn and Dpp are the neutron and proton pairing
energies as defined in Ame'83, p.56.
Unfortunately, the values given for the neutron-proton pairing
energies (written Dnp in Ame'93, Pa in Ame2003) in these files do
not correspond to the definition in Ame'83, p.56, but to an older
definition which used only 2 Sd (deuton separation energies):
1/2(-1)**(Z)[-Sd(A+2,Z+1)+Sd(A,Z)]
instead of 3:
1/4(-1)**(Z+1)[Sd(A+2,Z+1)-2Sd(A,Z)+Sd(A-2,Z-1)]
Although the formula with 2 Sd is still correct, we believe the
formula with 3 Sd to be better.
We kindly ask those to used these np-pairing to accept our
apologize, and be informed that the physics they derived from
them is essentially unchanged.
We thank Pr. Till von Egidy for pointing out the problem.
